Answer:
12.5 s
Step-by-step explanation:
If acceleration is constant, speed is proportional to time. To increase the speed by 50 km/h, the car will need an additional time given by ...
t/(50 km/h) = (20 s)/(80 km/h)
t = (20 s)(50/80) . . . . . multiply by 50 km/h
t = 12.5 s
It will take 12.5 more seconds for it to reach a speed of 130 km/h.
Y=4x+4
I think this is it u just have to simplify to get it to y=mx+b
<em>I would say that your answer is </em><em>44</em>
<span>It's easy enough. Solving looks like that: p(roll of 8)+p(roll of 12) =</span>
Hope everything is clear.
